Rare Breed Triggers FRT 15L3 Flat 3 Position Forced Reset Trigger FRT 15L3 FLAT UPC 000000000000
Product Description
Take your AR-15 platform to the absolute limit with the Rare Breed Triggers FRT-15L3® (FLAT) Single-Stage 3-Position Forced Reset Trigger (SKU: FRT-15L3-FLAT / UPC: 000000000000). Designed for shooters demanding superior speed, precise control, and uncompromising reliability, the FRT-15L3 features a flat-faced trigger shoe that ensures consistent finger placement and mechanical leverage. This duty-grade, drop-in system introduces an innovative 3-position selector (Safe, Semi, and Forced Reset), allowing operators to easily transition from a crisp, traditional single-stage semi-auto pull into the devastatingly fast mechanical forced reset mode for rapid follow-up shots.
Built to withstand the punishing cyclic rates of rapid fire, the FRT-15L3® is housed within a rigid 7075-T6 anodized aluminum cassette and driven by hardened, heat-treated 4140 steel internal components. By locking the trigger from being pulled until the bolt carrier group fully returns to battery, and then mechanically forcing the trigger forward, the FRT-15L3 eliminates trigger freeze and cyclic timing malfunctions. The unit ships complete with a custom ambidextrous safety selector, dual selector levers (long and short), and a dedicated set of anti-walk pins to secure the trigger group against harsh vibration and receiver pin-hole wear.
In standard Semi-Automatic mode, shooters experience a buttery-smooth, predictable 4.0 to 4.5-lb single-stage pull perfect for precision marksmanship. When switched to Forced Reset (FRT®) mode, the pull weight shifts slightly to 5.5–6.0 lbs while maintaining the identical single-stage feel. This allows operators to leverage the firearm's recoil impulse for exceptionally fast string split-times while remaining entirely within one-shot-per-pull legal compliance parameters. 100% designed, manufactured, and assembled in the USA.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits standard Mil-Spec AR-15 lower receivers. CRITICAL: Requires a full-auto M16-cut Bolt Carrier Group (BCG) to actuate the reset bar. NOT compatible with semi-auto cut BCGs, Colt lowers with sear blocks, or receivers with internal shelves. Due to the accelerated cyclic rate in FRT mode, an H2, H3, or VLTOR A5 buffer system is mandatory to prevent bolt bounce and out-of-battery malfunctions.
- Ensure the host firearm is completely clear, the magazine is removed, and the chamber is visually and physically verified empty before separating the upper and lower receivers.
- Remove the factory pistol grip, safety selector, detent, and existing trigger group components from the lower receiver.
- Drop the FRT-15L3 cassette into the receiver pocket and securely install the provided anti-walk trigger and hammer pins, ensuring the screws are snugged with a drop of blue threadlocker.
- Install the included 3-position Rare Breed selector drum, apply the long and short selector levers to your preferred sides using the provided T10 Torx screws, and reinstall your grip and detent spring.
- Perform a rigorous bench-level function check across all three selector positions (Safe, Semi, FRT) while manually cycling the bolt carrier to verify positive reset and hammer retention before live-fire staging.
Key Features
- 3-Position Selector Functionality: Seamlessly transition between Safe, Semi-Auto, and Forced Reset modes using the included proprietary ambidextrous safety selector.
- Flat Trigger Shoe Profile: The straight trigger blade promotes consistent lower-indexing finger placement for maximum leverage and a strictly linear pull.
- True Single-Stage Operation: Delivers a crisp 4.0–4.5 lb pull in Semi-Auto mode and a robust 5.5–6.0 lb pull in FRT mode for consistent trigger geometry.
- Mechanical Forced Reset: Actively forces the trigger forward upon bolt cycling, allowing for blisteringly fast follow-up shots without utilizing "bump" techniques.
- Duty-Grade Metallurgy: Precision-machined 7075-T6 aluminum housing paired with heat-treated 4140 steel internals for maximum durability under rapid-fire stress.
- Anti-Walk Pin System Included: Secures the drop-in cassette firmly inside the receiver, preventing pin walkout and safeguarding the receiver holes from elongation.
